95xw-67 (rice)
Characteristic 5xw-67 conventional rice variety, selected by crop Institute of Ningxia Academy of Agricultural Sciences, participated in the national northern rice regional trial from 2000 to 2001. The average unit yield of 692.Okg/667m2 in the first trial in 2000 was 11.4% higher than that of Qiuguang, which was not significant. In 2001, the average unit yield of 692.3kg/667m2 was 8.7% higher than that of Qiuguang, which reached a significant level. The average unit yield of 704.5kg/667m2 in the production test in 2001 was 18.7% higher than that of the control Qiuguang. The average growth period of the two-year regional test was 154.7 days, which was 3.2 days later than that of the control. Plant height 105.5cm, total grains per panicle 134.4, fruiting grains 84.4%, 1000-grain weight 26.7g. Seedling blast grade 3, leaf blast grade 0, ear blast rate 0% 46%. Head rice rate 57.1%-56.6%, chalky rice rate 66%-46%, chalkiness 7.3%-4.6%, amylose content 16.2%-18.7%, gel consistency 81~9Omm. After two-year regional test and one-year production test, the variety showed moderate maturity, good high yield, resistance to seedling blast, leaf blast, ear blast and medium rice quality.

1. The improved intensive cultivation: the tender seedlings with 3 leaves to 4 leaves should be planted early, the fields with good water sources should be planted early, the fields with poor water sources can be a little later, and both dry seedlings and water seedlings are suitable, but they should be fully fertilized, deeply ploughed and raked flat, strong seedlings should be selected as far as possible, and seedlings should be planted in shallow water; the spacing between rows and nests is 1 foot 3 inches, and the spacing of 3 individual plants in each litter is triangular. This planting method is sparse, sparse and dense, which reduces the competition between nutrients and sunlight to the greatest extent, and is beneficial to the individual development of plants, so it can increase production by a large margin, so it is the most advocated way of planting seedlings.
